2 Claims.

flexible extension hose terminating in a rigid tube or wand adapted torecelve various types of cleaning tools. Among such tools is a crevicetool having a tubular portion of circular cross section adapted totelescope or interfit with the hose wand which merges with a portion orblade of rectangular cross section of a size which may be projectedbetween the slats of Venetian blinds or the fins of home heatingradiators or the like. In many instances it is desired to combine thesuction effect with a brushing action for thorough cleaning, but apermanently affixed brush prevents efiective use of such a tool in caseswhere only limited space is available for inserting the tool.

I have developed a crevice tool having a brush which is quickly andeasily detachable from and attachable to the tool. Further, the brush isso shaped that it tends to break up a straight line suction effect andcause a lateral suction which is highly desirable in cleaning Venetianblinds and the like.

According to the invention, the brush has a portion of U-shaped crosssection adapted to be telescoped within the open end of the tool bladeand a pointed or V-shaped exposed portion having upstanding bristleswhereby when the tool is projected between the slats of a Venetian blindor the like the bristles will brush the slat and at least a part of thesuction effect will be in a direction generally at right angles to theslats surface. When it is desired to use the tool without the brush, thbrush is merely pulled out of telescoping relation with the tool proper.

It is a primary object of the invention to provide an improved crevicetool for attachment to the extension hose of a suction cleaner.

Another object of the invention is to provide a brush for a crevice toolof the above type which can be quickly and easily attached to andremoved from the tool.

Another object of the invention is to provide a crevic tool of the abovetype having a detachable brush which serves a dual function of acting asa brush and directing at least a portion of the air flow in a directiongenerally at right angles to the tool blade.

Other objects of the invention and the invention itself will becomeincreasingly apparent from a consideration of the following descriptionand drawings, wherein:

Figure 1 is a fragmentary plan view of a crevice tool embodying theinvention;

Figure 2 is an elevational view of the tool shown in Fig. 1;

Figure 3 is a plan view of the brush attachment illustrated in Figs. 1and 2; and

Figure 4 is a transverse sectional view taken along the lin 4-4 of Fig.3.

Referring now to the drawings, I have indicated generally at H] aconventional crevice tool comprising a tubular portion I I adapted totelescope over and have a tight fit with the wand of an extension hosecoupled to a suction cleaner. Portion H merges into a portion [2 ofrectangular cross section which preferably terminates in an end l3 cutangularly. The tool I0 is usually formed of metal or a suitable class ofmaterial.

The brush generally indicated at 14 comprises a frame I5, preferablyformed of plastic material, having a thin walled portion I6 of U formcross section and a thickened lip or edge portion 11. It will be notedthat lip 11 extends beneath the bottom wall of portion It a distancecorresponding to the thickness of the bottom wall of rectangular portion12 of tool l0 and extends laterally beyond each side wall of portion is.The bottom edge of lip I1 is cut angularly to correspond with end l3 oftool 10, as indicated at l8, whereby this edge together with side edges19 and 24 abut the end of tool portion l2 to limit relative telescopingaction between the tool and brush and form an effective sealtherebetween when brush portion [6 is projected within tool portion I2.

Lip I1 is of generally V shape in plan view, since I have found thisshape most effective when projecting the brush into corners and thelike. A plurality of holes are formed in the lip to receive brushbristles, as indicated at 22, the bristles being secured in any suitablemanner as by bonding or stapling. It will be noted that the lip wallsextend upwardly to be substantially flush with the top wall of toolportion l2 and form a recess, indicated at 23, adjacent the end of toolIll. The height of lip I! which includes the thickness of the framebottom wall forming the base of recess 23, substantially conforms to thedepth of the tool blade, indicated as portion [2 as illustrated in Fig.2. It will be apparent that when the tool is used either for suctioncleaning or blowing that the lip walls together with the upstandingbristles will tend to direct the air stream at right angles to the toolwhich is highly desirable for efficient cleaning when the tool isprojected between the slats of Venetian blinds or the like, since theair stream will be directed toward or I wish it to be understood that Ido not desire to be limited to the exact details-of construction shownand described, for obvious modifications will occur to a person skilledin the art.

What I claim is:

1. The combination with a'creyi'se'tool adapted to be attached to asuction cleaner extension'rhose and of the type having a blade withanuopening generally rectangular incross section, ofa i brush adapted tobe detachably secured to the tool,

wsaid' brush-comprising I a frame' formed of solid rigid material andhaying' a thin wall poi tiomof U cress section adapted -to be'-telescope'davithin the blade, the base of the frame of the U sectionsubstantially I conforming to the wid-th er the blade opening and theupstanding-legs=ofsaid seotion substantially: conforming to the depth ofthe blade opening whe'reby 'the framerormsa relatively tight fit W ith-the blade, the base of the U section extending forwardly of the bladeengaging portion, the extending portion having an upstanding thickenedperipheral lip having a height substantially conforming to the depth of5 the blade and adapted to abut the sides of the blade to form anupwardly open recess forwardly of="'the'=-blade, and brush bristl'es-=ex-tending upwardly from ithe lip whereby the" lip ivvall and bristleswill tend to deflect air at right angles to ithe blade during use of thetool.
